The figure, not drawn to scale, consists of 1 Rectangle C and 1 Square D whose areas are in the ratio of 3 : 1. Given that
310 of Rectangle C is shaded, what fraction of Square D is shaded?
Area of Rectangle C |
Area of Square D |
3x10 = 30 u |
1x10 = 10 u |

Area of Rectangle C is the repeated identity.
Shaded area of Rectangle C is the same as the shaded area of Square D.
LCM of 3 and 10 = 30
Fraction of Square D that is shaded
=
910 Answer(s):
910
